Given that,

Using the Division Property of Inequality, Paige was able to get x > 12 and solve the inequality -1/2x > -6.

According to the division property of inequality, if we divide an equation's two sides by the same number, the equation doesn't change.

Let's say you have two identically sized pizzas. You divide each one into halves and serve your buddies one half of each pizza. You will have equal pieces of both pizzas left over if you measure the remaining portions.

-1/2x>-6

Begin by finding the slope of the line through the given points, (-3,0) and (3,0):

m = (Y₂ - Y₁)/(x₂ - x₁)

The ratio of the volume of the large sphere to the volume of the small sphere is 125/8.

Given two spheres having surface areas of 100π square centimeters and 16π square centimeters, solve for the radius of each spheres using the formula for the surface area of sphere.

A = 4πr^2

Sphere 1 : 100π cm^2 = 4πr^2

r^2 = 25

r = 5 cm

Sphere 2 : 16π cm^2 = 4πr^2

r^2 = 4

r = 2 cm

Then, solve for the volume of each spheres using the formula:

V = 4/3πr^3

Sphere 1 : V = 4/3π(5cm)^3

V = 500/3 π cm^3

Sphere 2 : V = 4/3π(2cm)^3

V = 32/3 π cm^3

Getting the ratio of the volume of the large sphere to the volume of the small sphere,

A triangle PRS is an equilateral triangle.

An equilateral triangle is a triangle whose all the three sides are equal and each angle measures 60º.

To construct an equilateral triangle:

1) First draw a ray PQ.

2) Then, with P as center and radius equal to 5 cm, draw an arc to cut ray PQ at R.

⇒ PR = 5 cm

3) Then, with R as the center and radius equal to 5 cm, draw an arc to intersect the initial arc at S.

4) Join PS and RS.

Now, the triangle PRS is an equilateral triangle with each side length of 5 cm.

Now mathematically we prove that the triangle we've constructed is an equilateral triangle.

PR = PS                   .......................(the radius of the arc is same)

PR = RS                  .......................(the radius of the arc is same)

Hence by transitivity property,

PR = RS = PS  which is 5 cm

The sine of the angle is given by:

Then we have to find the equivalent on the first quadrant. 120º is on the second quadrant, hence:

180º - 120º = 60º.

The reference angle of the angle of -240º is of 60º.
